Application of horizontal well multi-lateral section fracturing technology in Dagang oilfield

The implementation of the fixed string staged fracturing sand perforation of 10-73H horizontal wells in Dagang oilfield has been introduced in this paper.In addition , the design principle , performance requirements , the fracturing parameters design of fracturing and fracturing operation situation have also been discussed.After successful fracturing , the well achieved good production effect , which indicates the fracturing techniques can be applied to Dagang oilfield , with the reservoir fracturing of low permeability and high pressure.
